Welcome to the INFOMAR Website

Did you know that at over 800 000 sq km Ireland’s marine territory is 10 times greater than the land?

INFOMAR is a twenty year programme to map the physical, chemical and biological features of Ireland’s seabed. This is important for the sustainable development of our valuable coastal and offshore waters. It is managed by both the Geological Survey and the Marine Institute. Please explore our site and let us explain how it works.
